Traffic signal operations play an important role in the safe and efficient movement of people,
goods, and vehicles through our roadway systems. According to the 2012 National Traffic Signal

In particular, the report stresses the need for routine signal timing updates to keep pace with
changes in population growth and traffic patterns.
